About As Anomalous As Mounds Can Get

The title refers to a circle of 11 earthen mounds located new Monroe, Louisiana; the Watson Break site. Local residents have known about the mounds for years, but archeologists weren't attracted to them until clear-cutting of the trees in the 1970s made the size and novelty of Watson Break all too obvious.

Just how anomalous is Watson Break? Archeologist V. Steponaitis, from the University of North Carolina, opined:

"It's rare that archaeologists ever find something that so totally changes our picture of what happened in the past, as is true for this case."

On what does Steponaitis base such a powerful statement?

  1. Watson Break is dated at 5,0005,400 BP (Before Present), some three millennia before the well-known Moundbuilders started piling up earthen structures from the Mississippi Valley to New York State. In other words, the site is anomalously early.
  2. Indications are that Watson Break was built by hunter-gatherers, but no one really knows much about them; there's an aura of mystery here.
  3. Watson Break consists of 11 mounds -- some as high as a two-story house -- connected by a peculiar circular ridge 280 meters in diameter. The back-breaking labor required to collect and pile up all this dirt is incompatible with the life style of mobile bands of hunter-gatherers.
  4. The purpose of the Watson Break complex escapes us. Why the mounds? Why the circular ridge? Can we just shrug it off as a "ritual site"?

Comment. If you have been following the archeological news stories, you have seen at least three items destined to "revolutionize" the prehistory of the Americas: (1) The Watson Break site; (2) The Monte Verde site (more than 12,500 years old, SF#112); (3) Kennewick Man (a Caucasian skeleton 9,300 years old in North America, SF#109).

Science Frontiers Sourcebook Project Reviewed in:


  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W.
